Garden Eggs Production

Garden Eggs

Botanical Name: Solanum melongena (L)

Suitable varieties: Long purple, Black beauty, Florida market, Ntrowa pa, Ojwanshua, Baby aubergines (Ravaya)

Climatic requirements: Garden eggs prefer relatively high day (320C) and night (210C) temperatures, thus require warm temperatures for optimum growth and development.

Source of planting material: Buy certified seeds from reputable seed companies.

Site selection: Garden eggs grow in well-drained soils with high organic matter content. Farm should be close to a reliable source of water supply for irrigation.

Land preparation: A thorough land preparation is important in enhancing early crop establishment and adequate weed control. Garden eggs respond very positively to organic matter therefore incorporate 30 tons/ha of decomposed farm yard manure into soil at least a fortnight prior to planting.
Propagation: Seeds may be nursed in a seed tray or seedbed. Prick out seedlings in seed trays into larger boxes at 2 leaf stage and transplant to the field at 5 leaf stage. Apply liquid manure (20kg-25kg cattle/poultry manure in 200L water) or solution of 6-10g per litre of compound fertilizer high in phosphorus (15-15-15/20-20-0 NPK), at 75ml (1 milk tin) per plant to the base if leaves of seedlings are pale. Alternatively, already prepared seedling nutrient such as MAP may be applied to boost root growth.

Planting: Plant seelings, preferably late afternoon at a square spacing of 90cmx90cm during the major wet season and 90cmx60cm in the minor season.
Seed rate: 350g to 500g per ha.

Nutrient requirements: 207kg/ha of N, 46kg/ha of P2O5 and 340 kg/ha of K2O.

Fertilizer application: Use soil analysis as a guide for fertilizer application. A general recommendation is 2-3 split application of 250kg to 400kg /ha (a total of 23g/plant) of 15-15-15 NPK compound fertilizer. Side dress at 4,8,12 and 16 weeks after planting and after each harvest apply 5g/plant of Potassium Nitrate (400g/ha).

Weed control: By mulching and regular hoeing.

Pest and Disease Control:
Pests: Eggplant Skeletonizer (Selepa docilis), Fruit borer (Leucinodes orbonalis), Pyralid Moth larva(Euzophra villora), thrips sp. and spider mites. These pests can be controlled by routine sprays of recommended insecticides.
Diseases: Fruit Rot (Phytophthora parasitica) and Bacterial Wilt (Pseudomonas solanacearum). Control by removing diseased plants, practice crop rotation, use of resistant cultivars and apply recommended pesticides.

Harvesting: Garden eggs usually start to bear about 2 months after transplanting and may continue to bear for 3 months or more. Harvest the fruit twice weekly while they are relatively young. Fruits must have shiny skin and attractive colour. During harvesting, cut the fruit from the branches with about 5cm stalk and calyx attached.

Yield: Yield of 15-40 tons/hs can be obtained depending on the variety and application of good agricultural practices.

Packaging: Fruits must be graded and packed into plastic baskets.
Operational Budget/Ha/Yr

Activity/Input Cost(Ghc)
Land rent 300.00
Land preparation 600.00
Seeds (100gx4) 100.00
Fertilizer 2600.00
Agro chemicals 100.00
Labour 5000.00
Total estimated cost 8700.00

Revenue
Average yield/ha = 40 tons =40,000 kg
Percentage loss of 5%
Available yield = 95/100×40,000kg = 38,000kg
Farm gate price/50kg = Ghc25
38,000kg/50kgxGhc25 = 19,000
Income = Ghc19,000
Net income = Ghc19,000-Ghc8,700
= Ghc10,300
Note: This budget does not include fixed cost and overheads.
